New! use i2c FRAM with RL-FlashFS

I am trying to setup an i2c F-RAM with RL-FlashFS, not really sure where to start, did not find anything helpful in the RL-Flash docs.
Is this possible? If so it would great if someone could point me in the right direction.

Fram is ramtron FM24V10
Micro is LPC1758

Appreciate the help.

You mean this: http://www.ramtron.com/products/nonvolatile-memory/serial-product.aspx?id=109

It's only 1Mbit - is it really worth doing a file system at all?

Yes it is tiny, however i need to store a few small log files on it, I thought it would easier to setup a filesystem and use stdio function verse having to store data directly to memory location. I guess I could split it up amongst my logs and setup ring buffers or something similar on the FRAM chip to store my files.

I will be writing the files in one go(replacing old file with new one minus few old messages on the top and new ones added to the bottom) so my overhead should not be that bad.

I already have a spi flash going so I cant just define the fs_spi_.. functions to behave like I2c
